Default values are undefined after upgrading to 3.3.0

Hi!

With 3.2.1 the default values were generated for most of the types. After upgrading to 3.3.0 all the default values are gone.

My test cases are available here: https://github.com/storybookjs/storybook/blob/next/examples/cra-ts-kitchen-sink/src/stories/docgen-tests/types/ts-types.tsx#L93

Here's an output of what I receive from the loader after upgrading to 3.3.0:
